rusn-Toon Fuse-Tools, of which the following is a' specification, reference being had to the accompanying drawings.

This invention relates to a new and use ful fuse tool and has relation more particularly to a device of this general character especially designed and adapted for use by miners or other blasters, and it is an object of the invention to provide a novel and improved tool of this general character which can be employed with convenience and facility for the necessary treatment of a fuse and for the attachment of a cap to a fuse.

It is also an object of the invention to provide a novel and improved tool of this general character of a plier type, and wherein the pivotally connected members are provided with coacting means for cutting, splitting or crimping.

Another object of the invention is to provide a novel and improved device of this general character including a punch adapted to be employed to form a cavity in a stick of dynamite or other explosive for the recep- ,tion of the cap of the fuse, and wherein a knife blade is provided for severing or cut-' ting the dynamite stick or the like.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved fuse tool whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise .more convenient and advantageous for use,

as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In orderthat 'my invention may be the better understood, 1 will nowproceed to describe the same with reference to the accom- Fig. 2 is a view in front elevation of the structure, as illustrated in Fig. 1, withcertain of the parts omitted; Fig. 3 is a view partly in top plan and partly in section of the device as illustrated Specification of Letters Patent.

in Fig. 1, with the knife in closed position, and,

Fig. A is a cross sectional view taken through the working end portion of one of the elongated members, as herein embodied.

As disclosed in the accompanying drawlngs, my improved tool comprises two elongated members A and B, the member A belng provided in its central portion, With a slot through which thesecond member B is directed. The portion of the member B within the slot 1 is pivotally engaged, as at 2, with the member A so that said members A and B have relative swinging movement, as in pliers. V

A side face of the member A has engaged therewith a magazine 3 adapted to contain a supply of caps, and preferably of a size to receive ten caps, which is the number generally employed in a work day.

The under face of the member A at one end thereof is provided with a longitudinally disposed groove l of a configuration lll cross section to receive an end portion of a fuse, and the adjacent end portion of the member B has removably engaged therewith a longitudinally disposed blade 5 adapted, when pressure is imposed upon the opposite end portlons of the members A and B, to split the portion of the fuse within the groove 4. In practice it is preferred that the cutting edge of the blade 5 be oppositely beveled.

The member A, in a side face thereof, and inwardly of the groove 4 is provided with a recess or pocket 6 to removably receive a blade 7, and the inner face of said member Y receive a blade 10 for coaction with the blade 7 hereinbefore referred to. The blades 7 and 10 coact to cut avfuse positioned there- Y between. The blades 7 and 10 are also provided with the recesses 11 coacting for crimping a cap on a fuse. The member A is provided in its outer face with a longitudinal groove or channel 12, in which is piv0tally engaged an end portion of a punch 14:, which punch is adapted for use in the forming of a cavity in the explosive stick for the reception of the cap of the fuse. The opposite end portion of the member A is also provided with a longitudinally disposed channelor groove 15, which normally received the knife bladeilti, and which blade has one end portion pivotally mounted within said groove or channel. The knife blade 16 is adapted for usein the cutting of a dynamite stick or the like.

From the foregoing description it is thought to be obvious that a fuse tool constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may beassembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

7 I claim:

l. A tool of the class described comprising two relatively movable members provided with recesses in adjacent side faces, coacting blades removably held within said recesses, the outer portion of a wall 'of the recess of one of the members being provided with a supplemental recess'to receive the blade carried by the second member, said supplemental recess being inwardly of the blade carried by the first named member.

2. A toolof the class described com rising two elongated members, one of sai bers being provided in its central portion with a slot through'which the second mem her is directed, the portion of the second member within the slot being pivotally engaged with the first member, adjacent end portions of the members having their opposed faces fiat, similar side faces of said end portions of the members being provided with elongated and longitudinally disposed recesses, blades removably mounted within said recesses, the outer marginal portion of the longitudinal wall of the recess in one of the members being provided with a supplemental recess to receive the working marginal portion of the blade of the second member, said supplemental recess being inwardly of the blade arranged within the main recess.
